我的這樣跑一個月了,也沒當掉過
7970的話大概會在 680mh ~ 720mh左右
"intensity" : "9",
"gpu-engine" : "1180",
"gpu-fan" : "0-90",
"gpu-memclock" : "1000",
"gpu-powertune" : "20",
"temp-cutoff" : "95",
"temp-overheat" : "90",
"temp-target" : "80",

谢谢分享！maybe my 7970还有潜力可挖啊，我用的是盈通卡，gpu-engine调到过1250，效率也达到过700mh多，GPU温度到了90多，风扇到一下了90%多噪音大得吓人，担心挂掉就给调低了，现在是自适应的gpu-engine频率，设定一定的GPU温度和风扇速度百分比。

"gpu-memclock" : "75", <============== 大爺你確定?

"gpu-memclock" 是用的"75", 但这个你可以试着调到更高，记得过去调到过1000多，印象是温度升高很快，主机重启了，后来调到比较低的数字，发现效率不会有下降，也比较稳定。另外：75的时候GPU Caps Viewer显示的 Current clock mem并不会是75，是在变化之中，似乎这个数字不会起决定性作用，但是太高会有不利。

同樣的設定放在 7850的話大概會在 320mh ~ 350mh左右

GPU核心频率一般在925~1000mhz，会自动调节。挖矿效率在550~600m左右，貌似和天气温度有关，天气凉快效率高，GPU温度在75~82，风扇负荷在70%左右，也能自动调节。
